About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SH
The SC200X450SH is a large-bore double-acting pneumatic cylinder delivering substantial push force—15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 200 mm bore, 40 mm piston rod, and 450 mm stroke, this tie-rod actuator is built for heavy industrial linear motion where high force and moderate speed are required.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments. Ports are standard PT3/4, and the adjustable air cushion (33 mm) decelerates the piston smoothly at stroke ends.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SH Is Used
Heavy Press & Clamping
Generates up to 28274 N of force at 0.9 MPa for powerful pressing, riveting, and clamping operations in metal fabrication and assembly lines.
Hot Environment Automation
Viton seals allow reliable operation in autoclaves, foundries, and drying ovens up to 150°C, where standard seals would degrade.
Material Handling & Lifting
Provides the high thrust needed for lifting heavy pallets, tilting large bins, or diverting heavy packages on industrial conveyor systems.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SH the Right Cylinder?
For applications needing even greater force, consider stepping up to the 250 mm bore SC250 series, which provides 24544 N push at 0.5 MPa. If a shorter overall length is acceptable, the 160 mm bore SC160 series offers 10053 N at 0.5 MPa. At 450 mm stroke, the 40 mm diameter rod has significant unsupported length; always guide the load externally or use a guided cylinder to prevent rod bending and premature bearing wear under side loads. For a direct replacement, match bore (200 mm), stroke (450 mm), PT port thread, built-in magnet (-S), and Viton seals (-H).
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SH FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200X450SH is a double-acting cylinder and will not hold position if air pressure is lost or the valve is centered. The piston will drift. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
